S220GD Galvanized Steel Coil | 1.0242
- John
S220GD galvanized steel coil is a high-quality steel product coated with zinc through a hot-dip galvanizing process. It not only resists corrosion and weathering but is also versatile. SteelPro Group’s hot-rolled and cold-rolled S220GD offers strong structural performance in environments where traditional steel might fail. It delivers dependability and enduring performance in applications ranging from roofing products to vehicle components.
S220GD Galvanized Steel Description
S220GD is a metal-coated structural steel designed to balance strength, formability, and corrosion resistance. It is a low-carbon steel substrate processed through continuous hot-dip galvanization. The “S220GD” designation indicates a minimum yield strength of 220 MPa. This steel offers excellent formability and superior surface quality, making it ideal for applications such as roofing sheets, wall cladding, and ventilation ducts.
SteelPro Group supplies S220GD primarily as coils and sheets, providing various coating options including S220GD+Z, S220GD+ZF, S220GD+ZA, and S220GD+AZ.

S220GD Steel Coil & Strip Surface Finish
S220GD galvanized steel is available in various surface qualities to meet diverse application needs. The classifications include:
NA (Normal Surface Finish)
This surface finish provides consistent zinc coverage. It is typically used for interior construction components and structural elements where surface appearance is not a priority.
MA (Medium Surface Finish)
This surface finish offers a smoother texture than NA. It is commonly used for exterior panels and cladding that require a balance of appearance and durability.
MB (High-Quality Surface Finish)
This surface finish delivers a more refined texture. It is ideal for automotive body panels and appliances that need a clean, uniform appearance before painting or coating.
MC (Critical Surface Finish)
This surface finish achieves exceptional smoothness and uniformity. It is often used for visible architectural elements where aesthetics are of paramount importance, particularly in coated steel applications.
